Sodium Chloride Induced pH and Temperature Responsive Biocompatible Hydrogel of Choline Oleate for Transdermal Drug Delivery of Doxorubicin

Abstract

AbstractNanodrug carriers have various biological and pharmaceutical applications, and among all the transdermal drug delivery is fascinating, specifically for localized medication therapy to a specific diseased organ or limited diseased area of the body, such as breast cancer cells or carcinoma cells. This way the efficacy of drug can be enhanced and its side effect to other healthy organs can be reduced to great extent. To ameliorate the limitations of traditional polymeric drug delivery systems, such as limited quantity and heterogeneity of the loaded drug, we developed a NaCl induced biocompatible gel of wormlike micelles of surface active ionic liquid (SAIL) i. e. choline oleate ([Ch][Ol]). Apart from the pH and temperature responsive mechanical properties, the designed gel also show good skin permeability, biocompatibility, adhesive qualities, stretchability, and viscoelasticity. The gel was tested for encapsulation of anticancer drug doxorubicin (DOX) and its transdermal delivery at pH=7.4 and pH=5.2. This system exhibits tremendous transdermal permeability of DOX and selective release more amount of the drug at 5.2 pH. Hence for localised and targeted delivery of an anticancer drug, this system can be proven to be suitable.
